There are lots of great games at

www.kidscount1234.com that I use with my first graders...

here are some others...

1. Top-it...use a deck of cards with 1-10...I use keno cards from a casino, but you can use a regular deck...take out jacks, queens, kings...basically the game is like War...set deck between 2 kids, each draws one card, lays it down, and the one with the highest takes both; if the card is the same value, each chooses another and lays them down and highest takes all cards...

Variations...

take 2 cards...add together and whoever has the highest sum takes the cards

2. Domino top-it...using a set of dominoes, turn them over in the middle of the table...two kids play, each draws a domino, adds the dots together and whoever has the highest number takes both dominoes, most dominoes at the end wins...

There are lots of great everyday math games to play...google everyday math games and lots of ideas come up...
